Seedling raising method for polygonatum cyrtonema seeds

Abstract

The invention provides a polygonatum cyrtonema seed seedling raising method, and belongs to the technical field of polygonatum cyrtonema cultivation. The polygonatum cyrtonema seed seedling raising method comprises the steps of sand storage, soaking in a potassium permanganate solution, soaking in a seed soaking solution for accelerating germination, sowing, covering placement after sowing and the like. According to the invention, the snow mountain extracting solution, the maidenhair root extracting solution and the gibberellin in the seed soaking solution can synergistically break the dormancy of the seeds and promote the germination of the seeds. The covering material is a mixture composed of pteridium aquilinum, bluegrass and humifuse euphorbia herb and has the functions of water permeability, air permeability and water retention, and meanwhile nutrient substances released by the covering material can promote growth of root systems of the seedlings and improve the quality of the seedlings. The polygonatum cyrtonema seed seedling raising method is beneficial to large-scale production of polygonatum cyrtonema seed seedlings, and sufficient high-quality seedlings are provided for planting of polygonatum cyrtonema.
